By modeling the fuzzy customer requirements, the retrieve model is more adapt to the E-business engineering fact. Refer to the special customer groups, the customer requirements can be translated into the certification and judgment for the attribute parameters of digital product feature. According to previous experience or the condition of using the digital product, customers can directly put forward quantitative or qualitative request to the attribute parameters of existing digital product feature of digital product series. In allusion to insufficiency of digital product retrieval based on similarity, the Neural Network is introduced into design of case retrieval and a model based Neural Network is proposed. By studying modeling NN and fuzzy requirements information, the mapping network from the parameters of digital product feature to the candidate of digital product has been set up. Rapid response to fuzzy individuation requirements of customer has been realized. This method, as the key technique of Ebusiness, is applied to gearbox design of enterprise, which can greatly shortened design cycle of no-standard digital product in digital product series.

Social commerce is expanding world and it has been introduced as a new method to increase sales, reduce marketing costs and increase customers. This approach is a combination of trade, individuals’ communications and webbased information technologies and so, the success comes from various factors. In this study, we will investigate success factors in implementing social commerce under the paradigm of pragmatism at the micro level. It was done by two methods: “inductive and deductive” in the qualitative phase in addition the adoption of pragmatism strategy, in-depth semi-structured interviews with experts and selected purposefully. In the qualitative part was to ensure validity and reliability by implementing the requirements provided in the notion of trust in addition to exploratory factor analysis. The data from the interviews were analyzed using content analysis so that forty-seven components were identified in six categories (Technical infrastructure and equipment, financial, human resources, culture, country’s rules and regulations, and style of management and business) and accordingly, the questionnaire was designed for the sector of quantitative. Using structural equation modeling was found that all factors were associated with the implementation of social commerce at a confidence level of 55% so that “technical infrastructure and equipment” and “style of management and business” are the highest and lowest impact on the mental model of social commerce implementation according to the process of formation of social commerce.

Background/Objectives: Today much attention is paid to the investigations in the sphere of computer-aided design (CAD), as the automation of difficult technical complexes (DTC) helps improve efficiency, quality and reliability. Methods: Over the recent years a great number of CAD methods other than classical have been developed. They become more complex and formalized; their implementation is associated with a large number of calculations; they are characterized by invariance in terms of the complexity of the designed system, etc. However, it has to be noted that modern requirements to DTC operations have set principally new problems that have to be solved in the process of DTC design. Thereat, to meet these requirements, it is often necessary to stand back from the classical principles of DTC design that have been formulated over half a century ago. In this context there is a great interest in applying the DTC development technologies that would help meet the set requirements. Findings: Founded on the category theory, this study suggests an approach to representing different-type DTC development technologies in a unified form convenient for their integration and coordination within the framework of DTC CAD cycle. Universal theoretical-categorical semantic mathematical models of those technologies have been suggested. According to the category theory, the systemic units (components, subsystems, systems, etc.) are the objects of the relevant categories; the operations are morphisms, the complex technological procedures are diagram structures. In the course of establishing structural alignment of different-type procedures that are predetermined within different categories the relevant functors of the categories have to be determined. Thus, the construct of the category theory enables clear and compact formalization of DTC CAD task. Applications/Improvements: The materials of the study are of practical value for the specialists engaged in solving DTC CAD tasks. Read More Read Less
